Abstract
Groove data for imparting a variation to one or more predetermined factors, such as generation timing, gate time and velocity, of a tone based on the automatic performance data are stored in a memory as a groove template. Further, modification data for modifying variation amounts of the predetermined factors are stored in the memory in a time series in corresponding relation to progression of an automatic performance. Automatic performance is carried out by modifying the variation amounts of the one or more predetermined factors in the groove template in accordance with the modification data and thus modifying the predetermined factors of the tone, based on the automatic performance data, in accordance with the thus-modified variation amounts.
